Thanks to KC (of MakeShopLive) I've got a great new product for you... I introduce the (switch to Super Hero voice) Cuppow! Made in the USA, the Cuppow allows you to turn a canning jar into a travel mug/beverage container! The idea is so simple, it's genius. Plus they've executed the design and packaging perfectly. I'll be using mine all spring/summer to take homemade lemonade along in the car. I also tested using it for hot tea and simply used an old tennis wristband as a cup sleeve.
Put that in your canning jar and sip it.
